iMac won’t turn on after upgrading RAM and SSD

I purchased 2 8GB RAM modules and 1 TB SSD to upgrade my extremely slow base model 2017 iMac. I followed the instructions meticulously, took me about 4-5 hours from start to finish and now the thing won’t turn on at all!

Where do I even start trying to troubleshoot the problem? Everything appears to be reconnected properly. I’m ripping my hair out as I need my computer for both work and school!

I took everything apart again to double check the RAM modules, noticed one appeared to be slightly damaged so I swapped it out with one of my old ones. Put everything back together and everything is working now.
